I've been using it for years now, it's working just fine for me. It's no Discord or WhatsApp just yet, but it's lacking about a couple hundred million dollars of investment for that to happen to any open source chat solution.

I'll happily move over to XMPP or IRCv4 if they can get it right, I'm not married to the way Matrix does things. But it's good enough, open source, and federated.
